Transfer case
!Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact a qualified specialist
workshop for a performance test.
!Because ESP®is an automatic system,
the engine and ignition must be switched
off (SmartKey in position0or1or Start/
Stop button in position0or1) when the
electric parking brake is being tested on a
brake dynamometer (maximum
10 seconds).
Braking triggered automatically by ESP®
may seriously damage the brake system.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always
transmitted to both axles.
Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and
explosion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.

conditions when temperatures are around
the freezing point.
For more information on driving with snow
chains, see (Ypage 407).
For more information on driving with summer
tires, see (Ypage 406).
Observe the notes in the "Winter operation"
section (Ypage 406).
Off-road driving
Important safety notes
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
GWARNING
If the vehicle level is high, the vehicle center
of gravity is raised. This could cause the
vehicle to tip over more easily on uphill or
downhill gradients. There is a risk of an
accident.
Select the lowest possible vehicle level.
When driving off-road, sand, mud and water,
possibly mixed with oil, for example, could get
into the brakes. This could result in a reduced
braking effect or in total brake failure and also
in increased wear and tear. The braking
characteristics change depending on the
material ingressing the brakes. Clean the
brakes after driving off-road. If you detect a
reduced braking effect or grinding noises,
have the brake system checked in a qualified
specialist workshop as soon as possible.
Adapt your driving style to the different
braking characteristics.
Driving off-road increases the likelihood of
damage to the vehicle, which, in turn, can lead
to failure of the mechanical assembly or
systems. Adapt your driving style to suit the
terrain conditions. Drive carefully. Have
damage to the vehicle rectified immediately
at a qualified specialist workshop.
Do not switch to transmission positionN
when driving off-road. You could lose control
of the vehicle if you attempt to brake using
the service brake. If the gradient is too steep,
drive backwards in reverse gear.
General notes
Read this section carefully before driving your
vehicle off-road. Practice by driving over more
gentle off-road terrain first.
Familiarize yourself with the characteristics
of your vehicle and the gear shift operation
before driving through difficult terrain.
The following driving systems are specially
adapted to off-road driving:
ROff-road program 1 and 2 (vehicles with the
ON&OFFROAD package) (Ypage 258)
RLOW RANGE off-road gear (vehicles with
the ON&OFFROAD package)
(Ypage 259)
RDifferential lock (vehicles with the
ON&OFFROAD package) (Ypage 259)
ROff-road ABS (Ypage 68)
RAIRMATIC package (vehicle level)
(Ypage 217)
RDSR (Downhill Speed Regulation)
(Ypage 256)
Observe the following notes:
RStop the vehicle before starting to drive
along an off-road route.
RFor vehicles with the AIRMATIC
package:select a vehicle level that is
suitable for the off-road terrain. To avoid
damaging the vehicle, make sure there is
always sufficient ground clearance.
RCheck that items of luggage and loads are
stowed safely and are well secured
(Ypage 345).

Driving and parking
Z

RAlways keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR (Ypage 256).
RAlways keep the doors, tailgate, windows
and sliding sunroof closed while driving.
RAdapt your speed to the terrain. The
rougher, steeper or more ruts on the
terrain, the slower your speed should be.
RDrive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
RDrive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
RLook out for obstacles, such as rocks,
holes, tree stumps and furrows.
RCheck the depth of water before fording
rivers and streams.
RWhen fording, do not stop and do not
switch off the engine.
ROn sand, drive quickly to overcome the
rolling resistance. Otherwise the vehicle's
wheels could become stuck in loose
ground.
RDo not jump with the vehicle as this will
interrupt the vehicle's propulsion.
RAlways keep the engine running and in gear
when driving on a slope.
RDo not shift the automatic transmission to
transmission positionN.
iDo not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients or on slippery or loose surfaces.
The HOLD function cannot hold the vehicle
on such surfaces.
Checklist before driving off-road
!If the engine oil warning lamp lights up
while the vehicle is in motion, stop the
vehicle in a safe place as soon as possible.
Check the engine oil level. The engine oil
warning lamp warning must not be ignored.
Continuing the journey while the symbol is
displayed could lead to engine damage.
XEngine oil level:check the engine oil level
and add oil if necessary.
When driving on steep gradients, the
engine oil level must be sufficiently high to
ensure a correct oil supply in the vehicle.
XDEF tank (BlueTEC vehicles):check the
level and top up if necessary (Ypage 186).
XTire-changing tool kit:check that the jack
is working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
XWheels and tires:check the tire tread
depth and tire pressure.
XCheck for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.
XReplace any missing valve caps.
XReplace dented or damaged wheels.
XRims:dented or bent rims can result in a
loss of tire pressure and damage the tire
bead. Therefore, check your rims before
driving off-road and replace them as
required.
Checklist after driving off-road
!If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist

Driving an d parking

Ruse in mountainous terrain or on poor road
surfaces
Rif the engine is often left idling for long
periods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.

Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
!For cleaning your vehicle, do not use any
of the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents
recommended and approved by Mercedes-
Benz.
Washing the vehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
Rwhen towing the vehicle
Rin the car wash
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
!Make sure that:
Rthe side windows and the sliding sunroof
are fully closed.
Rthe ventilation/heating is switched off
(the OFF button has been pressed).
Rthe windshield wiper switch is in position
0.
Otherwise, the vehicle might be damaged.

Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
